## Summary Fixes #12520 - Deleted chunks should not appear in retrieval/reference results. ## Changes ### Core Fix - **api/apps/chunk_app.py**: Include \doc_id\ in delete condition to properly scope the delete operation ### Improved Error Handling - **api/db/services/document_service.py**: Better separation of concerns with individual try-catch blocks and proper logging for each cleanup operation ### Doc Store Updates - **rag/utils/es_conn.py**: Updated delete query construction to support compound conditions - **rag/utils/opensearch_conn.py**: Same updates for OpenSearch compatibility ### Tests - **test/testcases/.../test_retrieval_chunks.py**: Added \TestDeletedChunksNotRetrievable\ class with regression tests - **test/unit/test_delete_query_construction.py**: Unit tests for delete query construction ## Testing - Added regression tests that verify deleted chunks are not returned by retrieval API - Tests cover single chunk deletion and batch deletion scenarios

Unit tests for delete query construction in ES/OpenSearch connectors.
|
||||
|
||||
These tests verify that the delete method correctly combines chunk IDs with
|
||||
other filter conditions (doc_id, kb_id) to scope deletions properly.
|
||||
|
||||
This addresses issue #12520: "Files of deleted slices can still be searched
|
||||
and displayed in 'reference'" - caused by delete queries not properly
|
||||
combining all filter conditions.
